Abstract
In order to easily and efficiently carry out various characteristic evaluations of optical fibers which have been laid down, a table file which is for carrying out association of optical fibers serving as measuring objects with measured data when the optical fibers have been measured, based on optical fiber management information provided in advance of undertaking a cable laying/maintenance construction, such as various types of information on the optical fibers serving as measuring objects, and information on a construction site, and the like, is created at an external terminal. An OTDR measures the optical fibers serving as measuring objects based on the table file created at the external terminal, and stores measured result data in which the measured optical fibers and measured data of the optical fibers have been associated with one another, and edited result data expressing edited contents when the table file and the measured result data have been edited. The external terminal generates a report based on the measured result data and the edited result data stored in the OTDR.
